THE REAL FRAUD IN WASHINGTON

Imran Awan was arrested at Dulles International Airport July 24, while attempting to board a flight to Pakistan. For more than a decade the congressional staffer had worked under top House Democrats, and he had just been accused by the FBI of bank fraud.

It was a dramatic moment in a saga that started in February, when Capitol Police confirmed an investigation into Mr. Awan and his family on separate accusations of government theft. The details are tantalizing: The family all worked for top Democrats, were paid huge sums, and had access to sensitive congressional data, even while having ties to Pakistan.

The media largely has ignored the affair, the ho-hum coverage summed up by a New York Times piece suggesting it may be nothing more than an “overblown Washington story, typical of midsummer.” But even without evidence of espionage or blackmail, this ought to be an enormous scandal.

Because based on what we already know, the Awan story is—at the very least—a tale of massive government incompetence that seemingly allowed a family of accused swindlers to bilk federal taxpayers out of millions and even put national secrets at risk. In a more accountable world, House Democrats would be forced to step down.

Mr. Awan, 37, began working for House Democrats as an IT staffer in 2004. By the next year, he was working for future Democratic National Committee head Debbie Wasserman Schultz. Over time he would add his wife, two brothers, a brother’s wife and a friend to the payroll—and at handsome sums. One brother, Jamal, hired in 2014 reportedly at age 20, was paid $160,000. That’s in line with what a chief of staff makes—about four times the average Capitol Hill staffer. No Democrat appears to have investigated these huge numbers or been asked to account for them.

According to an analysis by the Daily Caller’s Luke Rosiak, who has owned this story, the family has collected $5 million since 2003 and “appeared at one time or another on an estimated 80 House Democrats’ payrolls.” Yet Mr. Rosiak interviewed House staffers who claim most of the family were “ghost” employees and didn’t come to work. Only in government does nobody notice when staffers fail to show up.

The family was plenty busy elsewhere. A litany of court documents accuse them of bankruptcy fraud, life-insurance fraud, tax fraud and extortion. Abid Awan, a brother, ran up more than $1 million in debts on a failed car dealership he somehow operated while supposedly working full time on the Hill. One document ties the family to a loan from a man stripped of his Maryland medical license after false billing. Capitol Police are investigating allegations of procurement fraud and theft. The brothers filed false financial-disclosure forms, with Imran Awan claiming his wife had no income, even as she worked as a fellow House IT staffer.
